Microsoft Flight Simulator

The AMD Ryzen 5 5600X paired with the AMD Radeon RX 6750 XT in Microsoft Flight Simulator demonstrates a clear and predictable pattern of performance scaling across resolutions. The data shows that this combination is heavily GPU-bound, with the frame rate dropping significantly as pixel count increases, while the CPU maintains a stable foundation. At 1080p, the combo delivers 128.7 FPS on Low settings, which drops to 69.6 FPS on Ultra. Moving to 1440p, the same settings yield 102 FPS and 53.4 FPS respectively. At 4K, the burden on the GPU becomes severe: Low settings produce 70.9 FPS, while Ultra falls to 42.7 FPS. The gap between Low and Ultra at 4K is 28.2 FPS, identical to the 28.2 FPS gap at 1080p, but the percentage loss is much steeper at higher resolutions. This indicates that the RX 6750 XT's rendering pipeline is the primary constraint, not the Ryzen 5 5600X's six Zen 3 cores.

The scaling from 1080p to 1440p shows a 20.8% drop in average FPS on High settings (from 76.9 to 61 FPS). From 1440p to 4K, the drop is another 24.4% (from 61 to 46.1 FPS). The CPU's single-thread performance, evidenced by a Cinebench R23 single-core score of 2622 and a Geekbench single-core score of 2111, is sufficient to feed the GPU even at 1080p Low, where the frame rate peaks at 128.7 FPS. The 3DMark single-thread score of 917 further confirms that the processor is not the bottleneck in this simulation-heavy title. The data suggests that Microsoft Flight Simulator's complex flight model and world streaming benefit from the CPU's high clock speeds (base 3.70 GHz, boost 4.60 GHz), but the GPU's raw fill rate and memory bandwidth (432.0 GB/s) dictate the upper limits of visual fidelity.

FAQ

Q: Is the AMD Ryzen 5 5600X sufficient for Microsoft Flight Simulator at 4K?

A: Yes, the CPU is more than capable. The data shows no evidence of CPU limitation, as frame rates scale consistently with GPU load. At 4K Ultra, the combo still achieves 42.7 FPS, which is a playable result for a flight simulator, and the CPU's 78th percentile ranking among all CPUs supports its adequacy.

Q: How much performance does the RX 6750 XT lose when moving from High to Ultra settings?

A: At 1080p, Ultra is 7.3 FPS slower than High (69.6 vs 76.9 FPS). At 1440p, the difference is 7.6 FPS (53.4 vs 61 FPS). At 4K, the difference is 3.4 FPS (42.7 vs 46.1 FPS). The relative penalty shrinks at higher resolutions, but the absolute frame rate becomes more marginal.

Q: Does the game benefit from the GPU's 12 GB of VRAM?

A: The 12 GB GDDR6 memory, paired with a 192-bit bus, provides 432.0 GB/s of bandwidth. This is likely sufficient for the high-resolution textures used in flight simulators, as the performance drop from Medium to High at 4K (11.5 FPS) is less severe than from Low to Medium (13.3 FPS), suggesting memory capacity is not a hard limit.

Q: What is the best resolution for this combo to maintain 60 FPS?

A: To sustain an average of 60 FPS or higher, the data shows 1080p High (76.9 FPS) and 1440p Medium (79.6 FPS) both qualify. At 1440p High, the average drops to 61 FPS, which is borderline. For a stable 60 FPS experience, 1080p Ultra (69.6 FPS) is the safest choice.

Q: How does this combo's performance compare to the GPU's nearest rivals in synthetic benchmarks?

A: The RX 6750 XT's average benchmark score is 35327, placing it 0.2% above the RX 5600M, 0.3% below the RTX 5070 Ti Mobile, and 1.3% below the RTX 3080. These deltas are small, but the measured FPS in this game shows the 6750 XT handles the workload adequately, even if synthetic scores suggest a close grouping.

Q: Should I lower settings to Low at 4K for a smoother experience?

A: The data shows Low at 4K produces 70.9 FPS, which is 28.2 FPS higher than Ultra. If smoothness is the priority, Low at 4K is a viable option. However, the visual compromise may not be worth it, as Medium at 4K still delivers 57.6 FPS, which is closer to the 60 FPS target.

Settings Recommendations

The measured rows provide a clear hierarchy for optimal gameplay. For a balance of visual quality and frame rate, the Medium preset is the standout choice across all resolutions. At 1080p, Medium delivers 95.7 FPS, which is 33.0 FPS faster than Ultra and only 33.0 FPS slower than Low. At 1440p, Medium produces 79.6 FPS, which is a comfortable margin above the 60 FPS threshold. At 4K, Medium yields 57.6 FPS, which is playable for a flight simulator that does not require fast reaction times. High settings are a viable alternative at 1080p (76.9 FPS) and 1440p (61 FPS), but at 4K High drops to 46.1 FPS, which is below the Medium preset's performance.

The Ultra preset is only recommended for users with a display capped at 1080p, where it achieves 69.6 FPS. At higher resolutions, Ultra's visual gains do not justify the frame rate cost. Low settings are unnecessary for this hardware, as even the Medium preset provides more than double the frame rate of Low at 4K in some cases, while offering significant visual improvements. The data suggests that the Medium preset is the sweet spot, providing a 20.5% improvement over High at 1080p and a 30.4% improvement over High at 1440p, without the steep penalties of Ultra.

How This Combo Ranks

In the aggregate database of tested combinations for Microsoft Flight Simulator, this specific pairing of the Ryzen 5 5600X and RX 6750 XT ranks 853rd out of 1795 combos. This places it in the 47.5th percentile, meaning it outperforms roughly half of all tested systems while falling behind the other half. This is a solid mid-pack result, indicating that the hardware is well-matched for the game's requirements. The CPU alone holds a 78th percentile ranking among all CPUs, while the GPU holds a 79th percentile ranking among all GPUs, suggesting that the combination is not artificially limited by a weak component.

The rank of 853 reflects the game's demanding nature. Microsoft Flight Simulator is known for its heavy reliance on both CPU and GPU, and this combo's position in the middle of the pack is consistent with its component specifications. The Ryzen 5 5600X's Cinebench R23 multi-core score of 18578 and the GPU's PassMark G3D score of 20700 both indicate capable hardware, but the game's engine likely favors more powerful GPUs for the highest settings. The delta between this combo and the top performers is likely driven by the GPU, as the CPU's single-thread performance is competitive. For a user with a 1080p or 1440p monitor, this rank translates to a playable experience, but for 4K enthusiasts, the combo may require lowering settings to achieve acceptable frame rates.

GPU Role

The AMD Radeon RX 6750 XT plays a pivotal role in determining this game's performance, particularly at higher resolutions. The GPU's 12 GB of GDDR6 memory on a 192-bit bus provides 432.0 GB/s of bandwidth, which is essential for streaming the vast, detailed scenery in Microsoft Flight Simulator. The GPU's base clock of 2150 MHz and boost clock of 2600 MHz, with a game clock of 2495 MHz, allow it to maintain high throughput. The FP32 performance of 13.31 TFLOPS is a key metric, as the game's rendering of terrain and weather effects relies heavily on raw shader compute.

The measured FPS data reveals that the GPU is the limiting factor at all resolutions. At 1080p Low, the frame rate of 128.7 FPS is likely capped by the CPU's ability to issue draw calls, but even at this low setting, the GPU is not fully idle. As resolution increases, the GPU's pixel rate (166.4 GPixel/s) and texture rate (416.0 GTexel/s) become the primary constraints. The 40 ray tracing cores are present, but the game's measured scores do not isolate ray tracing performance. The GPU's 79th percentile ranking among all GPUs, with an average benchmark score of 35327, places it in the upper tier. Its nearest rival, the RTX 3080, scores 1.3% higher, but the 6750 XT still delivers playable frame rates at 4K with Medium settings (57.6 FPS). The GPU's memory bandwidth is also notable, as the 432.0 GB/s figure is critical for the high-resolution textures used in the simulator. The data confirms that the RX 6750 XT is the workhorse of this combo, and its performance characteristics dictate that users should prioritize the Medium preset for a balanced experience.
